BACKGROUND

The present disclosure relates generally to methods for user interface generation, but not exclusively, to a computer-implemented method for dynamically generating contextualized augmented reality user interfaces. The present disclosure relates further to a related system for augmented reality user interfaces, and a computer program product for operating such a system.

Virtual assistants are used by some companies, software producers, and device manufacturers to facilitate access or operation of a device or program by a user. Virtual assistants often listen for and respond to predetermined keywords linked to operations programmed for the virtual assistant. These predetermined keywords and functions may be established by a company associated with the virtual assistant.

Augmented reality systems are used by companies in photography, videography, and messaging applications. Often such augmented reality systems provide visual effects overlaid onto a video stream, in order to capture images or video containing the visual effects. Augmented reality systems may also provide predefined functionality, such as a heads up display for depicting driving directions.

DETAILED DESCRIPTION

The present disclosure relates generally to methods for user interface generation, but not exclusively, to a computer-implemented method for dynamically generating contextualized augmented reality user interfaces. The present disclosure relates further to a related system for augmented reality user interfaces, and a computer program product for operating such a system.

Virtual assistants are becoming prevalent in the home and outside. These virtual assistants may provide vocal interaction with speaker and microphone devices such as smart phones, smart speakers, smart homes, tablet devices, cars, and other mobile and stationary computing devices. Virtual assistants may also provide connection to and interaction with Internet of Things (IoT) devices and data sources. However, virtual assistants may be limited to small devices with no or limited visual interfaces. Users may encounter difficulties interacting with such virtual assistants and knowing varying navigation options or sources for the virtual assistants. Similarly, users may desire additional ways of interfacing with virtual assistants. In embodiments of the present disclosure, augmented reality devices may provide an additional interface option and provide technical solutions to interface issues between users and virtual assistants.

Augmented reality devices may enable an overlay of a user interface onto the real world, as seen by the user. However, augmented reality interfaces may be confused or uncoordinated, divorced from actions and movements of the user. Embodiments of the present disclosure enable dynamic generation of a contextualized augmented reality interface. Such contextualized augmented reality interfaces may enable a user to better interact with virtual assistants and an environment of the user. Further, inputs from the augmented reality devices may provide additional contextualizing input to enable virtual assistants to provide additional information regarding functions and selection options with a more economical user interface and without a display device dedicated to the virtual assistant.

Embodiments of the present disclosure may provide methods and systems for creation of a dynamic user interface being overlaid in an augmented reality or virtual reality device. These user interfaces may correlate user interface creation features by learning from user vocalizations and utterances. Further embodiments of the present disclosure utilize user and virtual assistant interactions and responses (e.g., successful responses and failed responses) to assist in contextualizing dynamically generated augmented reality and virtual reality user interfaces. Some embodiments of the present disclosure consider inputs from a global corpus (e.g., a global profile of users of the presently disclosed methods and systems) to assist in contextualization of user interfaces and user responses and interactions. Embodiments of the present disclosure may also receive and interpret interactions with IoT devices and IoT connected virtual assistants and display sources to present the dynamically created intuitive user interface to the user in an augmented reality or virtual reality environment. Further, embodiments of the present disclosure enable a user to interface with or connect to an API of an available service.

Some embodiments of the concepts described herein may take the form of a system or a computer program product. For example, a computer program product may store program instructions that, when executed by one or more processors of a computing system, cause the computing system to perform operations described above with respect to the computer implemented method. By way of further example, the system may comprise components, such as processors and computer readable storage media. The computer readable storage media may interact with other components of the system to cause the system to execute program instructions comprising operations of the computer implemented method, described herein. For the purpose of this description, a computer-usable or computer-readable medium may be any apparatus that may contain means for storing, communicating, propagating, or transporting the program for use, by, or in connection with, the instruction execution system, apparatus, or device.

Referring now to FIG. 1, a block diagram of an example computing environment 100 is shown. The present disclosure may be implemented within the example computing environment 100. In some embodiments, the computing environment 100 may be included within or embodied by a computer system, described below. The computing environment 100 may comprise an augmented reality interface system 102. The augmented reality interface system 102 may comprise a detection component 110, an ambiguity component 120, an artifact component 130, an interface component 140, and a profile component 150. The detection component 110 detects vocalizations and utterances at an augmented reality device. The ambiguity component 120 determines and quantifies relative levels of ambiguity of detected utterances. The artifact component 130 generates visual artifacts within an augmented reality user interface based on utterances and ambiguity levels of those utterances. The interface component 140 detects interactions with visual artifacts within the augmented reality user interface. The profile component 150 models user profiles and modifies profiles and models based on interactions detected by the interface component 140 corresponding to utterances detected by the detection component 110. Although described with distinct components, it should be understood that, in at least some embodiments, components may be combined or divided, or additional components may be added, without departing from the scope of the present disclosure.

Referring now to FIG. 2, a flow diagram of a computer-implemented method 200 is shown. The computer-implemented method 200 is a method for dynamic augmented reality interface creation. In some embodiments, the computer-implemented method 200 may be performed by one or more components of the computing environment 100, as described in more detail below.

At operation 210, the detection component 110 detects an utterance from a user of an augmented reality device. In some embodiments, the utterance may be captured through one or more of the augmented reality device (e.g., a smart glasses, a headset, a visor, a smartphone operating in an augmented reality mode), a virtual assistant, a mobile computing device (e.g., a smartphone or smart speaker), combinations thereof, or any other suitable device. The detection component 110 may detect the utterance using a microphone or other audio input of a suitable computing device. In some embodiments, the detection component 110 comprises, includes, or is part of a speech recognition application. The detection component 110 may also detect the utterance by receiving the utterance from another computing device or a virtual assistant. For example, the utterance may be detected by a smart speaker on which a virtual assistant is running. The smart speaker may transmit or pass the utterance, or portions thereof, to the detection component 110 via one or more communication protocols or connections. In this way, the detection component 110 may receive or detect utterances even when not directly connected to an audio input device such as a microphone.

In some embodiments, the detection component 110 initially detects the utterance as a vocalization. The vocalization may be detected at the augmented reality device, a mobile computing device, a virtual assistant device, or combinations thereof. The detection component 110 may detect mel-frequency cepstrum (MFC) representations of sounds within an audio stream. The detection component 110 may identify mel-frequency cepstral coefficients (MFCCs) that form the MFC. The MFCCs may be used as features, by the detection component 110, to recognize the vocalization as speech. The detection component 110 may extract the speech features from the audio stream and apply natural language processing (NLP) operations to recognize keywords within the audio steam. In some embodiments, the detection component 110 may recognize keywords by semantic content analysis using one or more NLP operations, functions, or applications. In some embodiments, the detection component 110 uses NLP analysis to determine the vocalization is an utterance containing keywords.

The detection component 110 compares the vocalization to one or more vocalization profiles. The vocalization profiles may be a data structure of historical utterances and functions or operations selected contemporaneous to the utterance. In some embodiments, vocalization profiles are models for historical usage of one or more users generated using utterances, keywords identified within utterances, functions associated with the utterances, frequency of usage for utterances, combinations thereof, and any other characteristics or aspects defining user interactions with the augmented reality interface system 102. In some instances, the detection component 110 compares the vocalization to one or more vocalization profiles by matching keywords of the utterance to keywords within the one or more vocalization profiles. Based on comparison of the vocalization to the vocalization profiles, the detection component 110 determines the vocalization is an utterance corresponding to one or more functions by looking up one or more functions, within the one or more vocalization profiles, associated with each keyword of the utterance.

In some embodiments, the one or more vocalization profiles includes a global profile. The global profile may represent utterances of a plurality of users. In some embodiments, the global profile defines utterance characteristics of the plurality of users. The detection component 110 may generate or build the global profile by capturing vocalizations and utterances of all users (e.g., crowdsourcing vocal interactions) of the augmented reality interface system 102. The detection component 110 may detect what users say, using MFCC based speech feature extraction and NLP enabled keyword and semantic content analysis. The detection component 110 may correlate the vocalizations and utterances of the users with applications, functions, operations, and IoT devices with which the vocalizations or utterances interact. The detection component 110 may then associate or otherwise link at least one function, operation, or device with each vocalization or utterance, or keywords found within the vocalization or utterance. In some instances, an image capture device or a camera may detect and capture user activity, using regional convolutional neural networks (R-CNN) for object detection within a geospatial environment. For example, where the utterance includes keywords associated with a camera enabled IoT device, the detection component 110 may employ R-CNN to detect a visual context of the utterance and operation of the IoT device associated with the utterance. The detection component 110 may determine a frequency of use of the vocalizations or utterances and correlated applications, functions, operations, or devices. The detection component 110 may use a recurrent neural network (RNN) or long short term memory network (LSTM) models to correlate functions or operations and vocalizations or utterances identified using NLP. The detection component 110 may generate the global profile as a function of utterances, operations, frequencies, and contexts for interactions across all users of the augmented reality interface system 102. In some instances, the global profile is stored in a cloud database with an anonymized record of credentials and sanitized transcripts for model training, testing, and updating.

In some embodiments, the one or more vocalization profiles includes a user profile. The user profile may represent historical utterances of the user of the augmented reality device. In some embodiments, the user profile defines utterance characteristics of the user of the augmented reality device. The user profile may be generated in a manner similar to that described above for the global profile. The user profile may be specific to the user of the augmented reality device such that vocalizations or utterances, correlated operations, frequencies, and devices may be tailored to or modeled on historical interactions of the user. In some embodiments, the user profile may be used to identify or model frequency of use of utterances and operations, context of operation or utterance usage, and other characteristics of the user's interactions with the augmented reality interface system 102.

In some embodiments, the detection component 110 compares the utterance or vocalization detected in operation 210 with MFCC speech features or NLP features identified or generated for the user and stored within the user profile. The detection component 110 may compare one or more of speech patterns, vocal register, word choice or vernacular, combinations thereof, or any other suitable voice or speech characteristics to speech characteristics stored within the user profile. Where the detection component 110 matches a sufficient portion of the speech characteristics in the vocalization or utterance with speech characteristics within the user profile, the detection component 110 may determine that the utterance is from the user. In such embodiments, the detection component 110 may select the vocalization profile of the user (e.g., the user profile) for use in the method 200. Where the detection component 110 fails to match a sufficient number of speech characteristics of the vocalization or utterance with those of the user profile, the detection component 110 may determine the vocalization or utterance is from an alternate user and select the global profile for use in the method 200. Further, in some embodiments, the detection component 110 may ignore a vocalization or utterance which fails to match speech characteristics of the user and the user profile.

In some embodiments, the detection component 110 provides a mechanism to allow a user to opt-in or opt-out of services provided by the augmented reality interface system 102. The opt-in/opt-out mechanism configures the detection component 110 according to user preferences such that any data collection (e.g., detecting vocal utterances) is done with the user's consent. Further, once the user performs opt-in or opt-out selections, the detection component 110 or the interface component 140 may pass the selections to the profile component 150. The profile component 150 may store the selected preferences within a user profile for the user. In some embodiments, the profile component 150 generates and transmits or displays a notification to the user indicating the change in the user profile regarding the opt-in/opt-out selection. Further, in some embodiments, based on user preferences for opt-in/opt-out and data collection, the artifact component 130 and the interface component 140 may generate and transmit or display a notification to the user when data collection occurs by any of the components of the augmented reality interface system 102, such as the detection component 110.

At operation 220, the ambiguity component 120 determines an ambiguity level of the utterance. The ambiguity level may be a quantification of an ambiguous nature of the utterance. The ambiguity component 120 may determine ambiguity for the utterance indicating an ambiguity associated with a source of data for actions or operations associated with the utterance. The ambiguity component 120 may determine ambiguity with an action or operation to be performed based on the utterance (e.g., which operation or function correlates to the utterance). The ambiguity component 120 may determine ambiguity regarding a context of the utterance.

In some embodiments, the ambiguity component 120 determines the ambiguity level by receiving keywords, determined for the utterance using NLP processing, from the detection component 110. The ambiguity component 120 may identify a plurality of operations and contexts associated with at least one keyword received from the detection component 110. The ambiguity component 120 may identify the plurality of operations and contexts associated with the keyword by accessing at least one vocalization profile (e.g., the global profile, the user profile, or both) and parsing the vocalization profile for keywords, associated functions, and associated contexts. The ambiguity component 120 may determine a probability that the utterance refers to each associated function based on the keywords of the utterance, the context of the utterance, and a frequency of use of the utterance and function. For example, a keyword of the utterance may be associated with three operations. The ambiguity component 120 may determine a first probability of seventy-five percent that the keyword is intended to refer to a first operation, a second probability of sixty-three percent that the keyword refers to a second operation, and a forty-nine percent probability that the keyword refers to a third operation. Based on the probabilities and the profiles, the ambiguity component 120 determines the ambiguity level as relatively high. For example, the ambiguity component 120 may determine the ambiguity level as a function of the three differing operations weighted against the probability determined for each operation.

At operation 230, the artifact component 130 generates a set of visual artifacts within an augmented reality user interface. The artifact component 130 may generate the set of visual artifacts based on the utterance and the ambiguity level. In some embodiments, each visual artifact of the set of visual artifacts corresponds to a selectable function. The set of visual artifacts may be generated as a dynamic user interface presented in an augmented reality context.

In some embodiments, the artifact component 130 generates each visual artifact of the set of visual artifacts as a visual representation of a function. Each visual artifact may be generated as a pop-up window, a dialogue box, a speech bubble, a shape with or without words, combinations thereof, or any other suitable and relevant visual representation of the function associated with the visual artifact. For example, where the utterance includes keywords of “open” and “music,” the utterance may be associated with initiating or opening two differing music applications stored on a mobile computing device. The artifact component 130 may generate two visual artifacts, each being associated with opening or initiating a different music application. The artifact component 130 may then present the two visual artifacts in an augmented reality user interface. For example, the artifact component 130 may generate a first visual artifact as a first icon of a first music application and generate a second visual artifact as a second icon of a second music application. The artifact component 130 may then display the first visual artifact and the second visual artifact as two boxes or icons floating above a smart speaker executing a virtual assistant. Where the user looks away from the smart speaker, the first and second visual artifacts may disappear or be removed from a field of view. Where the user returns the smart speaker to the field of view depicted by a pair of smart glasses displaying an ad hoc augmented reality user interface, the artifact component 130 may again display the first and second visual artifacts. Thus, the artifact component 130 may generate an ad hoc augmented reality or virtual reality user interface for a user based on the user's utterance, context, user profile or global profile, applications frequented by the user, devices frequented by the user, the user's previous commands, and one or more events.

At operation 240, the interface component 140 detects an interaction with a first visual artifact of the set of visual artifacts. The first visual artifact may correspond to a first selectable function. In some embodiments, the interface component 140 detects the interaction from an input device. For example, the interface component 140 may detect a user click of a mouse, having a pointer depicted within the augmented reality user interface. The input device may also be a touch screen (e.g., receiving a user's input and replicating it within the augmented reality user interface), a motion detector (e.g., detecting movement of the user and correlating the movement into actions within the augmented reality user interface), combinations thereof, or any suitable and relevant input device. In some embodiments, the interface component 140 cooperates with the detection component 110 to detect utterances or vocalizations of the user, identify a movement or interaction associated with the utterance or vocalization, and implement the interaction. For example, the detection component 110 may detect an utterance and determine the utterance refers to the first visual artifact. The interface component 140, in cooperation with the detection component 110, may detect the interaction with the first visual artifact. Although described with reference to a first visual artifact, it should be understood that the interface component 140 may detect interaction with any one or more visual artifact of the set of visual artifacts.

In some embodiments, once the interface component 140 detects the interaction, the interface component 140 may store an indicator for the interaction. The indicator may represent the first visual artifact, the first selectable function, the utterance, and the ambiguity level of the utterance. The interface component 140 may store the indicator as within a user log, incorporate the interaction within the user profile, or otherwise store the indicator for use by the augmented reality interface system 102.

In some embodiments, the profile component 150 modifies a vocalization profile of the user of the augmented reality device based on the indicator for the interaction. The profile component 150 may modify the vocalization profile of the user (e.g., the user profile) to increment or otherwise increase a frequency of use of one or more of an utterance, a keyword, an operation, a device, or an application associated with the indicator. In some embodiments, the profile component 150 modifies the vocalization profile after a threshold event occurs. The threshold event may include a time or interval, a number of interactions, a percentage of interactions, or any suitable and relevant threshold for modifying or updating the vocalization profile.

In some embodiments, the profile component 150 uses the indicator for the interaction as a form of feedback for the augmented reality user interface and the augmented reality interface system 102. The profile component 150 may use the indicator as implicit feedback or explicit feedback. Implicit feedback may evaluate learning operations or models of the augmented reality interface system 102 through observation or use. The profile component 150 may use implicit feedback as reinforcement learning, taking into account actions that are being performed by the user when interacting with the augmented reality interface system 102, IoT devices, or any other system or device. The profile component 150 may use implicit feedback as reinforcement learning, incorporating a time of interaction with the systems or devices with which interactions occurred. In some instances, the profile component 150 uses the implicit feedback to develop a pattern history or update a usage pattern for the user within the user profile.

In some embodiments, the profile component 150 uses the indicator as explicit feedback, taking into account a user's explicit actions or creation of augmented reality user interfaces in different devices (e.g., phone widgets, computer screens, augmented reality display modulation, etc.). The profile component 150 may use the explicit feedback to assist in building more intuitive designs in the augmented reality or virtual reality environment to keep track of the user's preferences. For example, the profile component 150 may monitor preferences of switching between different modes of user interface screens, a frequency of switching, a duration of switching, and an event precipitating the switch. The profile component 150 may also monitor preferences with respect to presentation styles for visual artifacts (e.g., presenting text boxes vs. application icons). In this way, the profile component 150 may enhance the accuracy in training a feedback module or the user profile to predict a user interface for a given context and a particular time.

At operation 250, the artifact component 130 modifies the augmented reality user interface in response to the interaction with the first visual artifact. The artifact component 130 may modify the augmented reality user interface by removing the set of visual artifacts, presenting one or more subsequent visual artifacts, terminating the augmented reality user interface, combinations thereof, or any other suitable and relevant modification. In some embodiments, the artifact component 130 initiates another application, program, operation, function, or device associated with the first visual artifact. For example, in response to selecting the first visual artifact, associated with a music application, the artifact component 130 may access an API or other documentation for the music application. Based on the API or hook of the music application, or other available service, the artifact component 130 may initiate playback of music within the music application, open the music application within a mobile computing device and the augmented reality user interface, or open or initiate the music application in a smart speaker or other IoT device. In some instances, where the artifact component 130 opens or initiates an application associated with the first visual artifact, the artifact component 130 may generate additional visual artifacts or user interface elements. For example, where the first visual artifact is associated with the music application, upon selection of the first visual artifact, the artifact component 130 may remove the first visual artifact and display user interface elements for the music application, such as a playlist, a play/pause button, a fast forward button, a back button, and other suitable visual artifacts.

In some instances, the user interface elements may be contextually displayed. In the example of the music application, the user interface elements may be displayed where a smart speaker, playing music, is in a field of view of the augmented reality user interface. Where the field of view excludes the smart speaker or the smart speaker exits the field of view, the artifact component 130 may modify the user interface elements to minimize or remove the music application. The music application may be resized or reappear where the smart speaker comes back into the field of view or where the user selects the user interface element or otherwise demonstrates a desire to access the music application.

In some embodiments, the artifact component 130 cooperates with one or more component of the augmented reality interface system 102 to modify an interaction with a virtual assistant in response to the interaction. The augmented reality interface system 102 may cause the virtual assistant, running on a device connected to or accessible by the augmented reality interface system 102, to perform one or more operations. For example, where the interaction is selection of a visual artifact associated with playback of music by a music application, the augmented reality interface system 102 may interact with a smart speak, on which the virtual assistant is operating. The augmented reality interface system 102 may pass the function associated with the selected visual artifact to the smart speaker. The function may initiate one or more operations by the smart speaker or the virtual assistant to execute the function, such as initiating playback of selected music through the smart speaker using the music application.

FIG. 3 shows a flow diagram of an embodiment of a computer-implemented method 300 for dynamic augmented reality interface creation. The method 300 may be performed by or within the computing environment 100. In some embodiments, the method 300 comprises or incorporates one or more operations of the method 200. In some instances, operations of the method 300 may be incorporated as part of or sub-operations of the method 200.

In operation 310, the artifact component 130 accesses one or more vocalization profiles to determine a set of action pairs based on an utterance and an ambiguity level. Each action pair is defined by an utterance and a corresponding function. In some embodiments, a single utterance is associated with more than one function, such that an utterance may be part of more than one action pair. For example, an utterance of “music” may be associated with functions for launching three different music applications, functions for initiating playback of music using each of the three different music applications, functions for terminating playback or closing each of the three different music applications, and other suitable functions.

In operation 320, the artifact component 130 ranks the set of action pairs based on one or more utterance characteristics of the one or more vocalization profiles. In some embodiments, the vocalization profiles include profile characteristics. Profile characteristics may include utterance characteristics, function characteristics, usage characteristics, history characteristics, and preference characteristics. Utterance characteristics may represent preferred vocabulary or commands indicating common commands uttered by a user and usage of the common commands. Usage of the common commands may represent a frequency of command usage, a time of command usage, a context of command usage (e.g., device context, event context, location context), and other suitable and relevant usage statistics. Function characteristics may represent preferred or commonly used functions accessed, launched, or executed by the user. Function characteristics may include information defining frequency of function usage, time of function usage, context of function usage, and other suitable and relevant usage statistics for functions or applications stored on one or more device. Usage characteristics may include the usage statistics described above. In some embodiments, usage characteristics correlate or otherwise associate utterances with functions, such that usage characteristics may indicate most commonly used utterances to perform the most commonly used functions. History characteristics may define a history of commands by the user, a frequency of commands over time, characteristics of command introduction (e.g., first use of a command, first function activated with a new command), characteristics of function introduction (e.g., time, location, and context of newly installed applications), commands rarely or no longer used, and other suitable characteristics indicating changes in usage of the augmented reality interface system 102 over time.

The artifact component 130 may rank the set of action pairs based on the profile characteristics defined for the global profile (e.g., a first vocalization profile) or the user profile (e.g., a second vocalization profile). In some embodiments, the artifact component 130 ranks the set of action pairs based on the global profile where profile characteristics for the user profile indicate the utterance is new or infrequently used by the user. The artifact component 130 may rank the set of action pairs based on the user profile as a default or where profile characteristics of the user profile represent a more accurate ranking.

In some embodiments, the artifact component 130 ranks the set of action pairs based on a context in which the utterance was issued (e.g., a location context, an event context, a time context, etc.), such that action pairs most related to a current context are ranked higher. The artifact component 130 may rank the set of action pairs based on a frequency of usage of the utterance (e.g., a frequency of usage globally or a frequency of usage by the user), such that action pairs for more commonly used keywords are ranked higher. The artifact component 130 may rank the set of action pairs based on a frequency of function usage, such that most commonly used functions (e.g., most common global functions or most common user functions) are ranked higher. In some embodiments, the artifact component 130 ranks the set of action pairs based on a plurality of profile characteristics, such that action pairs are ranked higher where the action pair is contextually appropriate, a keyword of the action pair is frequently used, and a function of the action pair is frequently used. Although described with respect to specified characteristics, it should be understood that the artifact component 130 may use any combination of profile characteristics to rank the action pairs.

In operation 330, the artifact component 130 selects a subset of the ranked set of action pairs. In some embodiments, the artifact component 130 selects the subset of ranked action pairs based on a relevancy threshold. The relevancy threshold may be a value associated with the ambiguity level or a probability of selection, such that action pairs having a low ambiguity level or a high probability of selection may be included in the subset of ranked action pairs. In some instances, the artifact component 130 selects the subset of ranked action pairs as a function of field of view within the augmented reality user interface. In such embodiments, the artifact component 130 may determine a total amount or percentage of the field of view, a size of the visual artifacts, and a font size of the visual artifacts, and dynamically select a number of action pairs for the subset of ranked action pairs which may be displayed within the percentage of field of view, with a suitable visual artifact size and font size. In some instances, the artifact component 130 selects the subset of ranked action pairs based on a specified threshold value. For example, the threshold value may be five visual artifacts. The artifact component 130 may select the top five ranked action pairs of the ranked set of action pairs for inclusion as five separate visual artifacts to be presented within the augmented reality user interface. In some embodiments, the artifact component 130 selects ranked action pairs based on a frequency of use of one or more of the utterance or the function. In such embodiments, the artifact component 130 may determine a number of ranked action pairs which are most frequently used for inclusion in the subset of ranked action pairs. The number of such subsets may be dynamically determined, determined based on user profile settings, or determined through any other suitable manner. Although described with respect to specified embodiments, it should be understood that the artifact component 130 may select any suitable number of ranked action pairs for inclusion in the subset of ranked action pairs.

In operation 340, the artifact component 130 generates a set of visual artifacts corresponding to the subset of ranked action pairs. The artifact component 130 may generate the set of visual artifacts in a manner similar to or the same as described above with respect to operation 230. In some embodiments, the artifact component 130 generates a separate or distinct visual artifact for each ranked action pair within the subset of ranked action pairs. In some instances, each visual artifact may comprise a logo or icon associated with the function of an action pair. For example, where an action pair includes a function of opening a music application, the visual artifact for the action pair may be an icon for the music application. In some embodiments, the visual artifacts may include text indicating the function to be performed. For example, where a first function of a first action pair opens a music application and a second function of a second action pair initiates playback of a recent playlist, the artifact component 130 may generate a first visual artifact with the icon of the music application and text reading “Open the App.” The artifact component 130 may generate a second visual artifact with an icon, logo, or representation of the recent playlist (e.g., an album cover) and text reading “Continue Favorites Playlist.” Each visual artifact may be linked to functionality within an application, user interface, or API, such that selection of the visual artifact connects to or triggers logic operations within a virtual assistant or mobile computing device to initiate the desired functionality.

Embodiments of the present disclosure may be implemented together with virtually any type of computer, regardless of the platform being suitable for storing and/or executing program code. FIG. 4 shows, as an example, a computing system 400 (e.g., cloud computing system) suitable for executing program code related to the methods disclosed herein and for dynamic augmented reality interface creation.
